Thoracic Manifestations
The thoracic CT findings of hypovolemia in patients who present with hemodynamic instability and injury have been investigated and described in detail [21]. In a study of 11 patients with hypovolemic symptoms, thoracic findings were
present in 81.8% of patients but completely absent in the rest. In patients who did display thoracic CT findings, at least
2 or more imaging manifestations were found. The most common findings (Table 3) include reduced calibre of the
thoracic aorta, decreased cardiac chamber volume, increased thoracic aortic enhancement, decreased calibre of aortic
vessels, decreased caval venous system calibre, and, finally,increased parenchymal enhancement in regions of pulmonary
contusion and/or collapse [21].
